FIELD OF THE INVENTION

The present disclosure relates to methods for treating a variety of diseases and/or ameliorating pain by administering to the ear canal of a subject a composition.

BACKGROUND OF THE INVENTION

Sympathetic presynaptic nerve cell bodies are located in the lateral horn of spinal cord segments T1-L2. Sympathetic postsynaptic cell bodies are in ganglia, either sympathetic chain ganglia or prevertebral ganglia. Sympathetic presynaptic fibers get to the sympathetic chain via white rami communicantes and either synapse at the level they enter, ascend or descend to synapse, or leave the sympathetic trunk without synapsing as a splanchnic nerve to go to a prevertebral ganglion. Sympathetic postsynaptic fibers may enter the spinal nerves via gray rami communicantes to be distributed with dorsal and ventral primary rami, may form perivascular plexuses to be distributed with blood vessels, or may travel to the target organ directly. The sympathetic nervous system provides sympathetic innervation to essentially every part of the body.

Parasympathetic presynaptic cell bodies are located in the brainstem and the lateral horns of spinal cord segments S2, S3, and S4 and leave the CNS in cranial nerves III, VII, IX and X, and in pelvic splanchnic nerves arising from the ventral primary rami of spinal nerves S2, S3, and S4. The parasympathetic postsynaptic cell bodies are located in four pairs of ganglia in the head (associated with cranial nerves III, VII and IX), and otherwise in microscopic ganglia either on or in the wall of the target organ. The distribution of the parasympathetic nervous system is more limited than the sympathetic nervous system, with cranial nerves III, VII and IX supplying smooth muscle and glands of the head, the vagus nerve supplying the visceral organs up to the left colic flexure, and the pelvic splanchnics supplying the descending and sigmoid colon, rectum and pelvic viscera. With the exception of the external genitalia, the parasympathetic nervous system does not reach the body wall.

The autonomic nervous system allows vertebrate species to go about their daily business without having to think about the mechanics of their organs. Hearts beat, intestines digest, blood vessels change diameter, and vertebrates adapt appropriately to any situation, all without our having to think about it.

SUMMARY OF THE INVENTION

The invention provides for methods for treating a variety of diseases that comprises performing topical auricular anesthesia of the external auditory canal for the purposes of anesthetizing cranial nerves 5, 7, 9, 10, 11, and 12, along with the parasympathetic nervous system, the sympathetic nervous system. In one embodiment, the invention provides for auricular anesthesia of the autonomic nervous system. In one embodiment, auricular anesthesia is performed on the trigeminal nerve, facial nerve, glossopharyngeal nerve, vagus nerve, accessory nerve, hypoglossal nerves, or a combination thereof. The invention further provides for modulation of the general somatic nervous system and the general visceral nervous system by administering an otic pharmaceutical composition comprising one or more anesthetics (such as lidocaine and/or tetracaine) in solution with a pharmaceutical carrier (such as an excipient) glycerine, and with or without epinephrine. In some embodiments, the otic pharmaceutical composition further comprises an analgesic, such as a pyrazolone derivative. In some embodiments, the pyrazolone derivative is antipyrene. The invention provides methods for treating a variety of diseases that comprises performing auricular anesthesia of the sympathetic nervous system via the vagus nerve to the sympathetic plexus. The invention also provides methods for treating pain from any variety of diseases disclosed herein by performing auricular anesthesia of the vagus nerve directly and the sympathetic nerve indirectly thus blocking general somatic afferent signals and general visceral afferent signals. The invention further provides methods of blocking pain from a variety of diseases that comprises performing auricular anesthesia of the vagus nerve with resultant anesthesia to the thalamic nuclei resulting in modulation of general visceral afferent pain and general somatic afferent pain. In various embodiments, the disease is a neurology-psychiatry-related affliction, an ear-nose-throat (ENT)-related affliction, a GU-related affliction, a gastrointestinal (GI)-related affliction, a cardiac-related affliction, a pulmonary-related affliction, or a metabolic-related affliction.

In various embodiments, the present invention provides a safe and non-invasive procedure, by which to treat a host of human diseases, and their symptoms, that are associated with the fifth cranial nerve (trigeminal nerve), the seventh cranial nerve (facial nerve), ninth cranial nerve (glossopharyngeal nerve), and the tenth cranial nerve (vagus nerve). The present disclosure provides a method of disrupting the normal physiological function of the nerve that does not rely upon an invasive and costly surgical procedure. The disclosed methods are able to “block” the transduction of both afferent and efferent signals from being transmitted via the trigeminal, facial, glossopharyngeal or vagus nerves. Such blockage of the transduction of signals on the nerve is achieved by a topical auricular anesthesia procedure, whereby a pharmaceutical composition is administered to the ear canal of a subject. It is the cutaneous auricular anesthesia of those nerves and their particular close proximity and relationship to their respective ganglia that allows for their modulation in function. It is that modulation of function which results in the modulation of expression of specific disease processes.

Thus, the present method applies generally to the treatment of any disease, ailment, or bodily condition that may benefit from the “blockage” of the particular nerve function. That is, any condition that would benefit from the hampered ability of the nerve to transmit neurological signals are encompassed by the disclosed method.

In methods disclosed herein, the pharmaceutical composition is administered to the ear canal of a subject in a concentration sufficient to physiologically alter the activity of the subject's nerve compared to the physiological activity of a nerve in a subject not administered the pharmaceutical composition. Thus, the present pharmaceutical composition utilized in a method as disclosed, is able to disrupt the natural ability of the nerve to transmit neurological signals along its length. These signals, both afferent and efferent, are blocked or hampered by the present methods.

The amount of analgesic present in the pharmaceutical composition comprises from about: 1 to 100 mg per mL, 10 to 100 mg per mL, 20 to 100 mg per mL, 30 to 100 mg per mL, 40 to 100 mg per mL, 50 to 100 mg per mL, 60 to 100 mg per mL, 70 to 100 mg per mL, 80 to 100 mg per mL, 90 to 100 mg per mL, or 100 mg per mL. In some embodiments, the amount of analgesic present is from about 50 to 60 mg per mL, or about 54 mg per mL, or about 50 to 55 mg per mL, or about 55 to 60 mg per mL.

The amount of anesthetic present in the pharmaceutical composition comprises from about: 1 to 100 mg per mL, 10 to 100 mg per mL, 20 to 100 mg per mL, 30 to 100 mg per mL, 40 to 100 mg per mL, 50 to 100 mg per mL, 60 to 100 mg per mL, 70 to 100 mg per mL, 80 to 100 mg per mL, 90 to 100 mg per mL, or 100 mg per mL. In some embodiments, the amount of anesthetic present is from about 1 to 20 mg per mL, or about 1 to 15 mg per mL, or about 5 to 15 mg per mL, or about 10 to 20 mg per mL, or about 10 to 15 mg per mL, or about 14 mg per mL.

The total amount of the pharmaceutical composition administered to a patient during one dosage may comprise from about: 0.001 to 0.01 mL of solution, or 0.01 to 0.1 mL of solution, or 0.1 to 0.5 mL of solution, or 0.1 to 1 mL of solution, or 1 to 1.5 mL of solution, or 1.5 to 2 mL of solution, or 2 to 5 mL of solution, or 5 to 10 mL of solution. The administration may comprise using a “dropper” bottle that applies “drops” of solution to the patients ear canal during a typical dosage. Such administration may comprise 1 mL 15-20 drops, 0.5 mL 10 drops, 0.25 mL 5 drops.

The pharmaceutical composition can comprise at least one anesthetic, at least one analgesic, or any combination thereof. For example, the composition can comprise one anesthetic, such as lidocaine; two anesthetics, such as lidocaine and bupivacaine; or an anesthetic and an analgesic, such as benzocaine and antipyrine.

The pharmaceutical composition can be provided in a solution comprising 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, or 95% of one or more anesthetics. In one example, the composition comprises 4% lidocaine and 2% bupivacaine.

As used herein, unless otherwise expressly specified, all numbers such as those expressing values, ranges, amounts, or percentages may be read as if prefaced by the word “about,” even if the term does not expressly appear. Any numerical range recited herein is intended to include all sub-ranges subsumed therein. Plural encompasses singular and vice versa; e.g., the singular forms “a,” “an,” and “the” include plural referents unless expressly and unequivocally limited to one referent.

In certain embodiments, the subject treated by the present methods does not have an ear infection. Furthermore, in certain embodiments, the subject treated by the present methods does not have an ear ache or is not experiencing ear pain.

In particular aspects, the present method is utilized on patients with ear infections. That is the present methods in certain embodiments specifically are utilized on patients with an external ear canal infection, with otalgia or with a middle ear infection, associated with or without purulence. Certain embodiments specifically utilize the methods on subjects experience an ear ache or ear pain. In these embodiments, a first step of method may comprise an ear examination by a treating physician to assure a patient does have an ear infection or is experiencing ear pain, or has a hole in the eardrum. It may consist of redness, middle ear effusion or swelling of the tissues of the external canal or distortion of the ear drum. In some aspects after ascertaining that the patient does indeed have an ear infection, whether it is in the ear drum, ear canal or middle ear, topical anesthesia in the form of Antipyrene/benzocaine dissolved in an excipient may be inserted in the ear canal in the form of an eardrop to reduce ear pain. This may also be done with lidocaine and tetracaine in a similar excipient of glycerine, with or without the presence of epinephrine. What is contraindicated is the usage of any topical anesthetic in the ear canal in the presence of an ear tube or pressure equalization tube or an active on going perforation.

The disclosed pharmaceutical compositions utilized in the present methods may comprise additional components such as: antibiotics, vasoconstrictors, glycerin, and acetic acid.

The pharmaceutical compositions may comprise any pharmaceutically acceptable carrier, or adjuvant, and may be formulated as: solutions, foams, gels, creams, pastes, lotions, emulsions, and combinations of the aforementioned.

The pharmaceutical composition may be administered once a day, twice a day, three times a day, four times a day, five times a day, six times a day, seven times a day, eight times a day, nine times a day, 10 to 20 times a day, or up to continuously throughout the day as needed. Further, in certain embodiments, the pharmaceutical composition is administered upon the onset of an asthma attack. In other embodiments, the pharmaceutical composition is administered upon a person feeling hungry. Some aspects of the methods entail administration of the pharmaceutical composition upon a patient feeling pain in their pharyngeal region. Certain embodiments contemplate not utilizing the taught compositions on patients that are experiencing ear pain, or that have an ear infection, or swelling in the ear associated with an ear infection. In these embodiments, the disclosed method of treating diseases associated with the vagus nerve may be immediately halted or stopped upon a patient developing ear pain.

A specifically preferred ailment to be treated by the disclosed method is the pharyngeal or oropharyngeal pain associated with a post-operative tonsillectomy or a post-operative adenoidectomy. These embodiments treat pain that patients feel after the aforementioned surgical procedures. In these embodiments, the pharmaceutical composition is applied to the ear canal of a subject that has had a tonsillectomy or adenoidectomy within: the preceding 168 hours (or 7 days), preceding 48 hours, preceding 24 hours, preceding 12 hours, preceding 4 hours, or immediately post-operation, prior to administering the pharmaceutical composition. Thus, the present method contemplates doctors prescribing the disclosed procedure and pharmaceutical composition to patients to utilize immediately upon feeling pain in the pharyngeal or oropharyngeal regions post-surgery.

Another particularly preferred ailment, or disease, to be treated by the disclosed method is asthma. In certain embodiments, acute asthma attacks are treated by the present methods. These embodiments involve administering the pharmaceutical composition to the ear canal of a subject that is presently experiencing an acute asthma attack. Further, these embodiments may comprise treatment of a subject that has experienced an asthma attack in the last 48, 24, 12, 6, or 1 hours. Thus, the methods taught herein may be used in conjunction with normal bronchodilators and corticosteroids for the treatment and management of a patient's asthma. The methods may be suitable for use on asthma patients experiencing a peak expiratory flow rate (PEFR) of 50 to 79% of the patient's normal peak flow readings, i.e. “the yellow zone” as classified by the American Lung Association. The methods are also suitable for use on a patient experiencing a peak expiratory flow rate of less than 50% of the patient's normal peak flow reading, i.e. “the red zone.” The methods can be utilized in conjunction with a rescue inhaler when a patient experiences a severe asthma attack. Consequently, in some embodiments, the present pharmaceutical composition is a component of a kit, wherein said kit comprises a rescue inhaler and a pharmaceutical composition comprising antipyrine and benzocaine. The kit is intended to be kept with a patient that is in danger of suffering a severe asthma attack. Further, in some embodiments, the pharmaceutical composition is part of an emergency first aid kit that is kept in school classrooms, for example. In these embodiments, teachers could utilize the present pharmaceutical composition in times of emergency, such as when a student suffers a severe asthma attack, but yet there is no rescue inhaler readily available.

The present methods are also suitable for use in treating chronic asthma. In these embodiments, patients utilize the disclosed compositions as taught in the present disclosure to prevent the onset of an acute asthma attack. In these methods, chronic asthma is managed by continuous use of the present methods. Thus, in certain embodiments, patients with asthma are administered the pharmaceutical compositions presented herein before the onset of an asthma attack. For example, certain embodiments of the present methods are effective at controlling asthma in patients that play sports. Often, patients suffering from asthma will experience a decreased ability to breathe upon physical exertion, which in some cases may lead to a severe asthma attack requiring the use of an inhaler. The present methods allow the treatment of a subject's ear canal with a pharmaceutical composition comprising antipyrine and benzocaine before the subject engages in playing a sport. In this manner, the present methods may be an effective therapy for patient's to utilize before engaging in physical activity, in order to reduce the likelihood of having an asthma attack.

Another particularly preferred condition, or disease, to be treated by the disclosed method is obesity. The present methods treat obesity by providing a mechanism to suppress a patient's appetite. By suppressing a patient's appetite, the present methods provide another tool for doctor's to utilize in managing a patient's weight. Thus, obesity may be treated by administering the taught pharmaceutical composition to a subject's ear canal. In some embodiments, subjects are treated with the taught pharmaceutical composition whenever the subjects experience a sensation of hunger. Further, some embodiments administer the disclosed pharmaceutical compositions to the subject's ear canal immediately before a meal is eaten, or 10 minutes to 60 minutes before a meal is eaten, or 20 to 60 minutes before a meal is eaten, or 30 to 60 minutes before a meal is eaten, or concurrently with the consumption of a food. Thus, in some aspects, the present method of auricular anesthesia of the vagus nerve is utilized on a patient within an hour prior to the patient eating any food. In this way, the patient's appetite is satiated and less food will be consumed. Further, some embodiments administer the disclosed pharmaceutical compositions to the subject's ear canal in the morning, preferably before the subject eats breakfast, thus providing an effective appetite suppressant that lasts until at least lunch.

In some embodiments, the present pharmaceutical compositions and treatment methodology are part of a comprehensive weight loss program that involves not only utilization of the pharmaceutical composition to curb a patient's appetite, but also may include a specific diet and exercise regime.

In some aspects, a person applying the topical pharmaceutical composition to a patient's ear canal should have good light, so as to get a superficial look into the patient's ear, so as to check for any gross obstructions, i.e. wax, skin, infection, purulence, or swelling. The person may gently pull the ear pinna outward and upward, so as to straighten out the ear canal. Ear drops comprising the taught pharmaceutical composition that have been previously warmed and are quite viscid should be applied to the posterior or back wall of the lateral ear opening. The drops should be applied very slowly and deliberately, one drop at a time, allowing for each drop to slowly migrate down the ear canal. The patient's head should be resting on its side on a flat soft surface for optimal application. The back wall of the canal and eardrum have a large portion of the vagal nerve fibers, and thus pointed application to this area is desired. In some aspects, children under 10 will require 4 to 8 drops per ear, while adults and children over 12 usually require 6 to 10 drops for anesthesia. In some embodiments, drops are always followed by a cotton ball in the lateral ear canal for about one hour to insure the maintenance of the medicine in the ear canal to provide the required topical anesthesia to the vagus nerve. After an hour the cotton may be removed.

The administration of a pharmaceutical composition to a patient's ear canal for the purpose of auricular anesthesia of the vagus nerve to treat a disease affected by vagus nerve physiological alteration is referred to in some embodiments as the “Crews Maneuver.” The Crews Maneuver of utilizing the ear canal as a conduit to anesthetizing the vagus nerve does not suffer from the drawbacks present in the art.

Aspects further comprise methods for ameliorating pain in a subject by administering to an ear canal of the subject afflicted with a distal pain an effective amount of a pharmaceutical composition comprising at least one anesthetic comprising Formula I described herein. In embodiments, a distal pain comprises a non-ear pain. The composition can further comprises at least one analgesic comprising a pyrazolone derivative.

Autonomic Nervous System.

The autonomic nervous system is divided into the sympathetic and parasympathetic components. The sympathetic nervous system prepares the body for stress and is called the “fight or flight” system. The parasympathetic system prepares the body for rest and is called the “rest and digest” or “vegetative” system.

The sympathetic nervous system is one of the two main divisions of the autonomic nervous system; the other being the parasympathetic nervous system. Sympathetic nervous system can be modulated or significantly affected by the usage of auricular anesthesia to the external auditory canal. Auricular anesthesia to the external auditory canal can modulate the vagus and glossopharyngeal nerves, which have direct connections to the sympathetic chain or nervous system (see FIG. 12, FIG. 13; see also FIG. 1 and FIG. 5). The primary process of the sympathetic nervous system is to stimulate the body's flight or fight response. It is however constantly active at a basic level to maintain homeostasis. It works as a compliment in intimate conjunction with the parasympathetic nervous system by direct neural communication.

There are two kinds of neurons involved in the transmission of any signal through the sympathetic nervous system: preganglionic or post-ganglionic. The shorter preganglionic neurons originate in the thoracolumbar region of the spinal cord (levels T1 to L2 specifically) to travel to a ganglion often one of the paravertebral ganglion where they synapse with a postganglionic neuron. From there, the long post-ganglionic neuron extends across most of the body. The sympathetic nerves arise from near the middle of the spinal cord in the intermediolateral nucleus of the lateral gray column, beginning at the first thoracic vertebrae of the vertebral column and are thought to extend to the second or third lumbar vertebrae. Axons of these nerves leave the spinal cord through the anterior root. They pass near the spinal sensory ganglion and they enter the anterior rami of the spinal nerves. However, unlike somatic innervation, they quickly separate out through white rami connectors that connect to either the paravertebral or the prevertebral ganglia extending alongside the spinal column. Presynaptic nerves or axons terminating either of the paravertebral ganglia or the prevertebral ganglia. In all cases, the axon enters the paravertebral ganglia at the level of its originating spinal nerve. After this it can either synapse in this ganglion, ascend to a more superior, or descend to a more inferior paravertebral ganglion and synapse there, or it can descend to a prevertebral ganglion and synapse there with the post-synaptic cell. Post-synaptic cell then goes on to innervate the target and effector, i.e. gland, smooth muscle, etc. Notable exceptions are the routes for innervation of the suprarenal adrenal medulla. In this case, the presynaptic neurons pass through the paravertebral ganglia onto through the prevertebral ganglia and then synapse directly with the suprarenal tissue. Auricular anesthesia to the vagus nerve can send signals to the paravertebral ganglia and affect neural transmission and thus affect sympathetic outflow to various organs, muscles, blood vessels, glands, skin, and nerves thus affecting disease processes.

The sympathetic nervous system is involved in hundreds of disease processes including the following: chronic fatigue syndrome, fibromyalgia, post-traumatic stress disorder, restless leg, anxiety, dysautonomia, hand tremors, migraine headaches, and muscle diseases such as multiple sclerosis, cerebral palsy, and Parkinson disease. Other diseases such as peripheral neuropathies, arthritis, reflex sympathetic dystrophy, muscle aches, sweating, orthostatic hypotension, postural orthostatic tachycardia syndrome, vasovagal reflex, cardiac arrhythmias, hypertension, diabetes, elevated blood sugar, elevated cholesterol, irritable bowel disease, irritable bowel syndrome, chronic constipation, ulcerative colitis, eclampsia, preeclampsia, HELLP syndrome, premature ejaculation, supraventricular tachycardia, and congestive heart failure can all be affected by an overactive sympathetic nervous system. Modulation of this system can be accomplished by directly modulating the parasympathetic nervous system via the auricular branch of the vagus nerve and the glossopharyngeal nerve and its intimate connections with the superior cervical sympathetic ganglion with its connections to the rest of the sympathetic nervous system, please see pending figures. It should also be noted that functions of the sympathetic nervous system also include dilation of pupils, increased in drying of the eyes, increased drying of the nose and the mouth, increasing the heart rate and force of contraction, dilation of bronchials, dilation of skeletal muscles, dilation of blood vessels going to the brain, decreasing blood flow to the kidney, decreasing blood flow to the gastrointestinal tract, increasing activation of sweat glands inhibiting peristalsis, increasing levels of renin, increasing levels of cholesterol and triglycerides, increasing levels of blood pressure, and promoting ignition for ejaculation.

The present invention provides for a method of treating or ameliorating symptoms in a subject with a disease associated with a particular cranial nerve, wherein the disease is a neurology-psychiatry-related affliction, an ear-nose-throat (ENT)-related affliction, a GU-related affliction, a gastrointestinal (GI)-related affliction, a cardiac-related affliction, a pulmonary-related affliction, or a metabolic-related affliction.

General visceral and afferent fibers conduct sensory impulses usually pain and reflex sensations from the viscera, glands, and blood vessels to the central nervous system. They are considered to be part of the visceral nervous system not the autonomic nervous system. However, unlike the efferent fibers of the autonomic nervous system the afferent fibers are not classified as either sympathetic or parasympathetic. General visceral afferent create referred pain to activating general somatic afferent fibers where the two meet in the posterior horn of the spinal cord. The cranial nerves that contain general visceral afferent fibers include the facial nerve, the glossopharyngeal nerve, and the vagus nerve all of which innervate the external auditory canal. General visceral afferent referred pain can be modulated by auricular anesthesia to these cranial nerves as they provide sensory innervation to specific areas of the external auditory canal. Topical anesthesia to these areas can modulate general visceral afferent signals from the body back to the central nervous system.

General somatic afferent fibers (GSA or somatic sensory nerves) afferent fibers arrive from cells in the spinal ganglia and are found in all the spinal nerves, except occasionally the first cervical, and conduct impulses of pain, touch, and temperature from the surface of the body through the posterior roots of the spinal cord and impulses of muscle sense, tendon sense, and joint sense from the deeper structures. General somatic afferent fibers travel through the sympathetic chain into the spinal nerve into the dorsal root ganglion into the dorsal root and into the spinal cord. It can travel up the spinal cord to the central nervous system to the thalamic level and then onto the cerebrum where they can be involved in a reflex arch involving visceral motor and somatic motor nerves which also travel from the ventral root back through the sympathetic chain to their respectful organs. FIGS. 12-13. It is not known at this time whether the modulation of the sympathetic paravertebral and prevertebral nervous system modulates pain at the ganglion or at the thalamic level at this time. Without being bound by theory, general somatic afferent pain and general visceral afferent pain can be modulated through auricular anesthesia topically applied to the external canal modulating the vagus nerve and its attachments to the sympathetic nervous system.

Vertebrate anatomy has many common neurologic anatomic and physiologic aspects. There is no reason to preclude the usage of topical anesthesia or auricular modulation of the external auditory canal for purposes of modulating disease via cranial nerves and the sympathetic nervous system in other vertebrate species namely primates, felines, canines, bovines, and rodent species. Without being bound by theory, other vertebrate species can also benefit from the treatment of specific cranial nerve-associated diseases by way of auricular modulation of the autonomic nervous system. The method comprises topically administering to an ear canal of a vertebrate subject a pharmaceutical composition comprising: i. an analgesic, and/or ii. an anesthetic to the external auditory canal.

Cranial Nerves.

The vagus nerve, also known as cranial nerve X, is the tenth of twelve paired cranial nerves and is the longest of the cranial nerves. Upon leaving the medulla between the medullary pyramid and the inferior cerebellar peduncle, it extends through the jugular foramen, then passes into the carotid sheath between the internal carotid artery and the internal jugular vein down below the head, to the neck, chest and abdomen, where it contributes to the innervation of the viscera. The anatomy of the vagus nerve is illustrated in FIGS. 1 and 2.

Upon exiting the jugular foramen, the vagus nerve forms the jugular ganglion and the ganglion nodosum or the superior and inferior vagal ganglion. The jugular ganglion is joined by filaments from the petrous ganglion of the glossopharyngeal nerve. The auricular branch of the vagus nerve also has connections from the jugular ganglion of ten and the petrous ganglion of the glossopharyngeal nerve as it enters the mastoid canaliculus from the lateral wall of the jugular fossa. Brushing the temporal bone, the auricular branch of vagas exits the tympanomastoid fissure and divides into two branches; one joins the post-auricular nerve and the other is distributed to the skin of the back of the ear and to the posterior external acoustic meatus.

The vagus nerve conveys sensory information about the state of the body's organs to the central nervous system. Approximately 80% of the nerve fibers in the vagus nerve are afferent, or sensory nerves, communicating the state of the viscera to the brain, while the remaining 20% are efferent, or functional nerves.

The vagus nerve is responsible for regulating a host of bodily functions, including, but not limited to, breathing, speech, sweating, facilitating in keeping the larynx open during breathing, monitoring and regulating heartbeat, and digestion of food in the stomach, along with a host of other physiological functions.

Consequently, manipulation of the vagus nerve and subsequent alteration of its normal physiological function may have profound effects upon a wide range of human ailments that are associated with vagus nerve regulation. However, the present procedures available in the art for altering the function of the vagus nerve are highly invasive. These current procedures often rely upon the implantation of artificial mechanical devices into the body of a patient. Besides being highly invasive surgical procedures, these methods are very costly.

For instance, the United States Food and Drug Administration approved a procedure called vagus nerve stimulation (VNS) in the late 1990s for the treatment of partial onset epilepsy. VNS is performed as a surgical procedure to install a pacemaker-like device into a subject suffering from epileptic seizures. The device, implanted inside a patient's neck area, is used to send mild electrical impulses through the vagus nerve. The device is battery operated, and has an electrical pulse generator. After it is implanted, electrodes with insulated plastic are run into the vagus nerve from under the skin on the patient's neck. The pulse is set to operate alternately, by turning on every few seconds and then turning off.

Researchers have also begun to investigate the possibility of utilizing these pacemaker-like devices in the stomach of obese patients to block the function of the vagus nerve, in order to suppress appetite. Again, these procedures are highly invasive and involve the implantation of artificial devices into the body of a patient.

Some surgeons have even performed vagotomy procedures to treat obesity. In these procedures, the surgeon completely severs a patient's vagus nerve. While these procedures successfully allowed the subjects to lose weight, it is apparent that such an invasive and permanent surgical procedure is problematic for many patients.

Cranial nerve seven or the facial nerve is one of the twelve paired cranial nerves (see FIG. 3). It is so named because its main function is to supply motor innervation to the muscles of the face. Other muscles it innervates are the platysma, the posterior belly of the digastric, and the stapedius muscle. The sensory and parasympathetic portion of the facial nerve travels in the nervus intermedius and supplies the following components: (1) taste to the anterior two-thirds of the tongue; (2) secretory and vasomotor fibers to the lacrimal gland, the mucus glands of the nose and sinuses, mouth, and the submandibular and sublingual salivary glands; and (3) cutaneous sensory impulses from the external auditory meatus and regions of the back of the ear. It is also thought that a parasympathetic impulse from the nervus intermedius, to the sphenopalatine ganglion, to the mucosa and submucosa of the nose and paranasal sinuses determines their venous capacitance and level of congestion.

The parasympathetic portion of the seventh cranial nerve takes its origin in the nucleus salivatorius in the brain stem and enters the interior acoustic meatus separate from the motor division of the facial nerve. It combines with the facial nerve proximal to the geniculate ganglion. The fibers leave the geniculate ganglion through the great superficial petrosal nerve and are joined by the large deep petrosal nerve to form the vidian nerve, or the nerve of the pterygoid canal, where together they move forward to synapse in the sphenopalatine ganglion. There they provide parasympathetic innervation to the eye, nose, sinus, palate, pharynx, and salivary glands. The geniculate ganglion receives general somatic afferent fibers from the external auditory canal via the auricular branch of the vagus nerve and its connection to the seventh cranial nerve. General somatic sensory afferent fibers synapse in the geniculate ganglion.

The trigeminal nerve or the fifth cranial nerve is the fifth of twelve paired cranial nerves and is the largest of all the cranial nerves (see FIG. 4). It is the great sensory nerve of the skin of the face, scalp, ear canal, the mucus membranes and other internal structures of the head. It also has functions as motor innervation to the muscles of mastication and contains proprioceptive fibers. It further carries sensory innervation from the dura of the brain with its various branches. The fifth cranial nerve is quite extensive. The main sensory nucleus extends from the pons to the upper spinal cord. The nucleus receives its afferent fibers from the semi-lunar ganglion, also known as the Trigeminal ganglion or the Gasserian ganglion. The Trigeminal ganglion contains the cell bodies of the sensory fibers for its three main divisions. It receives three large sensory division: the ophthalmic, maxillary, and mandibular divisions. The sensory root fibers leave the ganglion posteriorly to pass their insertion into the pons.

The glossopharyngeal nerve, also known as the ninth cranial nerve, is the ninth of twelve paracranial nerves that is known as the tympanic nerve and has both sensory and secretory fibers (see FIGS. 5 and 6). The nerve is a mixed sensory and motor nerve. The sensory component consists of somatic afferent fibers supplying sensation to the mucus membranes of the pharynx and tonsillar region and back of the tongue. The superficial origin of the glossopharyngeal nerve from the brain stem is by three or four rootlets in the groove between the olive and the inferior peduncle. It exits the skull through the jugular foramen and runs anteriorly between the internal carotid artery and the internal jugular vein. Upon exiting the jugular foramen, it forms a pair of ganglionic swellings: the superior or jugular ganglion, and the inferior or petrosal ganglion. The ganglion contains cell bodies of the sensory fibers of the nerve. The ninth nerve communicates with the vagus nerve or the tenth cranial nerve, the facial nerve, and the sympathetic ganglion. The glossopharyngeal nerve has five distinct general functions: (1) motor (special visceral efferent) supplies the stylopharyngeus muscle; (2) visceral motor (general visceral efferent) provides parasympathetic innervation of the parotid gland; (3) visceral sensory (general visceral afferent) carries visceral sensory information from the carotid sinus and carotid body; (4) general sensory (general somatic efferent) provides general sensory information from the skin of the external ear, internal surface of the tympanic membrane, upper pharynx, and posterior one-third of the tongue; and (5) special sensory (special afferent) provides taste sensation from the posterior one-third of the tongue, including circumvallate papillae.

The accessory nerve or the spinal accessory nerve is cranial nerve 11. The cranial nerve controls the sternocleidomastoid muscle and the trapezius muscle. The sternocleidomastoid muscle tilts and rotates the head while the trapezius muscle has several factors on the scapula including shoulder elevation and abduction of the arm. Range of motion and strength testing in the neck and shoulders can be measured during a neurological exam to assess the function of the spinal accessory nerve. Limited range of motion or poor muscle strength indicate damage to the spinal accessory nerve. This can be the result from a variety of causes of the cranial nerves. The spinal accessory nerve exits the cranium through a specialized hole or foramen. The nerve originates in the majority of individuals in the neurons situated in the upper spinal cord. From there, the fibers enter the foramen magnum and course along the inner wall of the skull toward the jugular foramen through which it exits the skull with the glossopharyngeal (or 9th cranial nerve) and the vagus nerve (or the 10th cranial nerve) owing to is peculiar course the spinal accessory nerve is notable for being the only cranial nerve to both enter and exit the skull (FIG. 1, FIG. 2, and FIG. 5). Once the nerve exits the jugular foramen, it crosses the internal jugular vein around the level of the posterior belly of the digastric muscle. It courses on to innervate the trapezius and sternocleidomastoid muscles. Function of the spinal accessory nerve is special visceral efferent or innervation and function of the motor control of the sternocleidomastoid and trapezius muscle. Abnormalities of the spinal accessory nerve can cause spasm of these two muscles along with fasciculation and weakness or aberrations in head, neck, shoulder, and arm movements and range of motion. The spinal accessory nerve is intimately connected to the vagus nerve that is the superior and inferior ganglion of the vagus nerve. Auricular anesthesia of the vagus nerve directly modulates electrical input and function of the spinal accessory nerve (see FIG. 5).

The hypoglossal nerve is the 12th cranial nerve, and innervates the muscles of the tongue. The nerve arises along with the other cranial nerves in the brain stem. The nerve exits the skull base in the posterior fossa through the hypoglossal canal. As it exits the skull, it gives off a small meningeal branch and picks up a branch from the anterior ramus of C1. It follows in near proximity to the vagus nerve and the spinal position of the accessory nerve and it follows behind the vagus nerve and passes between the internal carotid artery and the interior jugular vein lying on the carotid sheath. It passes deep into the posterior belly of the digastric muscle in the submandibular region. It passes lateral to the hyoglossus muscle in the inferior laryngeal nerve to reach and efferently innervate the tongue. It is intimately involved in speech as it innervates the tongue. It innervates intrinsic and extrinsic muscles of the tongue and is characterized as general somatic efferent nerve type. It can be modulated by indirect modulation or anesthesia to the vagus nerve, which directly communicates to the hypoglossal nerve (see FIG. 1 and FIG. 5). The hypoglossal nerve is involved in speech, as well as swallowing to clear the mouth of saliva and other involuntary activities completed by the tongue. Most functions are voluntary. Voluntary functions require conscious thought and nerve pathways occur in the corticobulbar region of the spinal cord. The hypoglossal nucleus is supplied by innervation from the reticular formation by which it is involved in several reflexive or automatic motions and in aiding unconscious movement required upon engaging in speech and articulation. Modulation of signals to the hypoglossal nerve via the 10th cranial nerve may have profound effects on the improvement of articulation, speech, swallowing, and posterior fossa headaches.

Thus, there is a great need in the medical community for methods of treating vagus and other cranial nerve associated diseases that are not dependent upon altering the function of the vagus nerve or other cranial nerves through invasive surgical procedures or artificial devices. Specifically, there is a great need in the art for procedures to alter the function of the vagus and other cranial nerves that are non-invasive, safe, effective, and economical

Disrupting Transduction of Neurological Signals Along the Cranial Nerves.

The present invention provides for methods of treating a variety of diseases disclosed herein that comprises performing auricular anesthesia (e.g., topical anesthesia) of the external auditory canal for the purposes of anesthetizing cranial nerves 5, 7, 9, 10, 11, and/or 12. The present invention also provides for methods of treating a variety of diseases disclosed herein that comprises performing auricular anesthesia (e.g., topical anesthesia) of the sympathetic and/or parasympathetic nervous system(s). The present invention further for methods of treating a variety of diseases disclosed herein that comprises performing auricular anesthesia of general visceral afferent, general somatic afferent, general visceral efferent, and/or general somatic efferent nerves. In some embodiments, auricular anesthesia is performed in a variety of vertebrate species including but not limited to species such as humans, horses, cows, pigs, dogs, cats, etc. In some embodiments, auricular anesthesia is performed by way of administering a combination of lidocaine and tetracaine combined in solution with an excipient glycerin with and without the presents of epinephrine. Antipyrine and Benzocaine can also be used in conducting auricular anesthesia of the external auditory canal for the purpose of treating diseases (see Examples herein). Glycerin is a usp based substance of the excipient. Tetracaine may also be administered without epinephrine to obtain similar results. Other excipients will also be utilized to carry the topical anesthetic or topical analgesic. In one embodiment, the present disclosure provides a method for treating symptoms of a disease which comprises topically administering to an ear canal of a subject a pharmaceutical composition comprising of an anesthetic and another anesthetic. In some embodiments, an analgesic with an anesthetic may also be utilized. This would be a separate eardrop in and of itself. In one embodiment, the analgesic is antipyrine, but could also consist of other known analgesics. In an embodiment, the anesthetic is at least one of a selected group consisting of an amide or an ester compound discussed herein.

The tenth cranial nerve (vagus nerve) is associated with numerous bodily organs and alteration of its normal physiological function can have profound effects on a host of human ailments. That is, by “blocking” or “disrupting” or “numbing” the conduction of neurological signals in the particular nerve, one is able to influence a host of organs that are innervated by that nerve. Consequently, blocking the transduction of signals transmitted along the nerve, whether those signals are afferent or efferent in nature, will alter the normal physiological response of various organs and tissues. This, in turn, can have profound implications for treating a variety of diseases, or ailments that are associated with human organs and tissues that are innervated by the particular nerve.

Auricular anesthesia of the cutaneous portion of the seventh cranial nerve (facial nerve) carry signals back to the geniculate ganglion where parasympathetic fibers and sensory fibers are anesthetized, blocked, or otherwise modulated. Anesthesia of the geniculate ganglion and its connection to the Sphenopalatine ganglion serve to modulate or block transduction of efferent signals through the facial nerve. This can profoundly affect disease processes such as, but not limited to, allergic rhinitis, vasomotor rhinitis, inflammatory nasal polyposis, chronic sinusitis, chronic nasal congestion, allergic conjunctivitis, sneezing, and rhinitis in all forms.

The sensory aspect of the fifth cranial nerve (trigeminal nerve) deals with information from the dura, the mucus membranes of the eyes, the mucus membranes of the nose and sinuses, the skin of the external auditory canal eardrum. Auricular anesthesia of the skin of the ear canal then signals to the trigeminal ganglion via the auriculotemporal branch of the mandibular division of the trigeminal nerve. Modulation of afferent signals through the trigeminal ganglion has profound effects on multiple disease processes. Modulating those afferent signals from the dura, the eye, the nose and sinuses leads to modulation of various disease processes. Manipulation of dural signals that pass through the ophthalmic, maxillary, and mandibular divisions have profound effects in the treatments of headaches and migraine headaches. Manipulation or modulation or blockage of afferent signals from the ophthalmic and maxillary divisions of the trigeminal nerve will result in modulated efferent signals from the motor division of the seventh cranial nerve that deal with allergic rhinitis, vasomotor rhinitis, all forms of rhinitis, inflammatory nasal polyposis, chronic sinusitis, chronic nasal congestion, allergic conjunctivitis and sneezing.

Auricular anesthesia of the cutaneous portion of the ninth cranial nerve (glossopharyngeal nerve) and its proximity to the petrous ganglion and its connection to the seventh cranial nerve and tenth cranial nerve can have profound effect on certain disease processes. Because of neural connections between the glossopharyngeal nerve and those of the seventh and tenth cranial nerves, disease processes specific to those nerves may also be modulated. Diseases specific to the glossopharyngeal nerve that may be affected by topical auricular anesthesia include, but are not limited to, pharyngeal pain, post tonsillectomy pain, sneezing, and parotid salivation.

Thus, several embodiments of the present invention comprise a method that blocks the transduction of efferent signals via the vagus, trigeminal, facial, or glossopharyngeal nerves. Another embodiment of the disclosure blocks the afferent transduction of signals via the vagus, trigeminal, facial, or glossopharyngeal nerves. The present disclosure also provides a methodology by which both the afferent and efferent signal transduction via the vagus, trigeminal, facial, or glossopharyngeal nerves is blocked.

While the methods for treating various diseases associated with the vagus and other cranial nerves have been described in the application in connection with various embodiments, the scope of the methods is not intended to be limited to the particular embodiments so disclosed. But on the contrary, the methods are intended to cover such alternatives, modifications, and equivalents, as may be included within the scope and spirit of the below claims.

Example 11—Treatment of Diseases

Embodiments of the invention comprise modulation of the general somatic afferent nerves and general visceral afferent nerves, by administering one or more anesthetic(s), (for example, either alone or in combination, such as Lidocaine or Bupivicaine) in solution with a carrier, such as an excipient, Polyetheylene Glycol. “Modulation” can refer to the ability of the compounds and/or compositions described herein to either enhance (i.e., stimulate) or inhibit (i.e., block) the activity of nerves, such as one or more of cranial nerves, general somatic afferent fibers, general visceral afferent fibers, and the like. For example, the general visceral afferent fibers (GVA) conduct sensory impulses (usually pain or reflex sensations) from the internal organs, glands, and blood vessels to the central nervous system. They are considered to be part of the autonomic nervous system. Embodiments described herein can modulate the general visceral afferent fibers, such as those of the vagus nerve.

The invention further provides for the modulation of the sympathetic and parasympathetic nervous systems, by auricular anesthesia to auricular branches of the vagus, glossopharyngeal, and facial nerves and their connections to the sympathetic ganglion. Anesthesia to the ganglion of cranial nerves 5, 7, 9 and 10, and the sympathetic nervous system results in their respective downward modulation. Overactive sympathetic and parasympathetic nervous systems are clearly implicated in the development and metastasis of certain types of malignancies, namely Prostate Cancer, Ovarian Cancer, Breast Cancer, and Lymphoblastic Leukemia.

Embodiments of the invention comprise treating, preventing, or providing symptomatic relief of infection-related afflictions. The term “infection-related affliction” can refer to an affliction that comprises or results from the invasion of a subject's body and/or body tissue by microorganisms, their multiplication, and the reaction of the subject's immune system to the microorganism. Non-limiting examples of infections as described herein comprise those of the Herpes Simplex virus (HSV type 1 or HSV type 2, for example) and the Varicella-zoster virus (VZV).

Embodiments of the invention comprise treating, preventing, or providing symptomatic relief of skin-related afflictions. The term “skin-related affliction” can refer to an affliction that comprises or affects the integumentary system which covers the entire surface of the body and is composed of skin, hair, nails, and related muscles and glands. Skin-related afflictions can be temporary or permanent. Non-limiting examples of skin conditions comprise facial flushing (such as Hot Flashes), facial blushing, Alopecia Areata, Atopic Dematitis, Chronic Eczema, Acne Vulgaris, Oily Skin, Rosacea, or Morgellons Disease.

Embodiments of the invention comprise treating, preventing, or providing symptomatic relief of cell proliferation-related afflictions. The term “cell proliferation-related affliction” can refer to an affliction that comprises or results from the uncontrollable proliferation of cells within a subject's tissues and the reaction of the subject's immune system to the cell proliferation and/or growth. Non-limiting examples of cell-proliferation related conditions comprise cancers (e.g., solid tumors and liquid cancers) and mastocytosis.

Embodiments of the invention comprise treating, preventing, or providing symptomatic relief of blood flow-related afflictions. The term “blood flow-related affliction” can refer to an affliction that is characterized by alterations in the flow of blood through a subject's vascular system and/or alters the flow of blood through a subject's vascular system. For example, a blood flow-related affliction can result in an increase in the flow of blood through a subject's vascular system. As another example, a blood flow-related affliction can result in a decrease in the flow of blood through a subject's vascular system. Non-limiting examples of blood flow-related afflictions comprise erectile dysfunction, sickle cell disease, or wound healing.

A test of an embodiment of the present method was conducted to evaluate the efficacy of the method for treating patients suffering from an infection-related affliction, cardiac-related afflictions, metabolism-related afflictions, gastroenterology/urology (GU)-related afflictions, skin-related afflictions, neurology-psychiatry-related, cell proliferation-related afflictions, and blood flow-related afflictions. Subjects suffering from such afflictions were instructed to utilize drops of a pharmaceutical composition comprising lidocaine (4%) and bupivacaine (2%), in one or both ears, at least one time per day (for example, either in the morning or at night), for a period of time as needed (Tmt Time).

Example 12—Treatment of Pain

Embodiments of the invention further comprise treating pain, such as pain that results from a variety of diseases disclosed herein, by performing auricular anesthesia that indirectly anesthetizes paraspinal and paravertebral ganglion. Those respective ganglion receive general visceral afferent signals that are thus modulated. Those modulated signals travel from the paraspinal and paravertebral ganglion to the dorsal root ganglion, then to the dorsal grey horn of the spinal cord, where they meet with general somatic afferent signals. Modulated general visceral afferent signals modulate the general somatic afferent signals by this invention, thus modulates pain in both nervous system pathways.

Embodiments of the invention comprise methods of blocking pain from a variety of diseases that comprises performing auricular anesthesia of the ear canal and concha, resulting in anesthesia to branches of cervical nerves 2 and 3 (C2, C3) and cranial nerves 5, 7, 9, and 10. The tenth cranial nerve, or Vagus Nerve, has direct attachments to the eleventh (11) and twelfth (12) cranial nerves and the sympathetic ganglion.

As is known in the art, pain is typically treated by administering an anesthetic or analgesic directly to the site of the pain. For example, U.S. Pat. No. 6,093,417 (Petrus) teaches administration of a topical ear composition comprising a penetration enhancer directly to the ear itself for the purpose of reducing inflammation of the inner ear and providing pain relief of the inner ear. However, as described herein, the invention provided for a method for ameliorating pain in a subject comprising administering to the ear canal of a subject a pain relieving composition so as to ameliorate pain at a distal site (i.e, non-ear pain, away from the site of composition administration).

A test of an embodiment of the method described herein was conducted to evaluate the efficacy of the method for treating patients suffering from pain. Subjects suffering from pain were instructed to utilize drops of a pharmaceutical composition comprising antipyrine (≈54.0 mg) and benzocaine (≈14.0 mg) (treatment protocol, “AB” Tmt Protocol) or drops of a pharmaceutical composition comprising lidocaine (≈40.0 mg) and tetracaine (≈5.0 mg) (treatment protocol, “LAT” Tmt Protocol), in one or both ears, at least one time per day (for example, either in the morning or at night), for a period of time as needed (Tmt Time). The LAT otic solution used in the tests comprises 4% Lidocaine, 0.5% Tetracaine, 1/100,000 Epinephrine, and Anhydrous Glycerine. The AB otic solution used in the tests comprises 5.4% Antipyrine, 1.4% Benzocaine, Oxyquinoline Sulfate, and Anhydrous Glycerine.
